Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535094, here are decompositions:

11 + 31535083 = 31535094
13 + 31535081 = 31535094
37 + 31535057 = 31535094
61 + 31535033 = 31535094
83 + 31535011 = 31535094
113 + 31534981 = 31535094
181 + 31534913 = 31535094
223 + 31534871 = 31535094

Showing the first eight; more decompositions exist.

IPv4 address

Federal Reserve district 3 (Philadelphia)

Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.
